Title: Improvements in and relating to the production of resilient material for stuffing upholstery, mattresses and the like
IPC: D04H1/68
Filed: 1936-12-08
Abstract: 489,031. Sponge rubber; agglutinated fibrous materials. TALALAY, J. A. Dec. 8, 1936, Nos. 33634/36 and 7600/37. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 14, 1937.] [Classes 70 and 87 (ii)] [Also in Group VIII] Spongy masses of rubber reinforced with fibrous material and suitable for example for use as upholstery filling are made by causing a dispersion or solution of rubber or the like to extend itself as a foam under the action of pressure reduction through the interstices of a bulky fibrous mass having its fibres bonded or locked together and then causing the rubber to set whilst permeating the fibrous mass. Fibres specified are hog hair and horsehair, cellulose fibre, asbestos, coconut fibre, wool, cotton &c. The fibres may be bonded together by an adhesive such as a rubber dispersion, casein, gelatine and rosin ; adhesives such as gelatine or rosin may be subsequently removed by means of a suitable solvent. Alternatively the fibres may be locked together in the form of a felt or a woven or knitted fabric with or without an adhesive. The foam may be produced by the processes described in Specification 455,138. The rubber dispersion may be prefrothed. The impregnated fibrous mass may be subjected to a carding operation before setting and subsequently moulded ; or moulded articles may be produced directly. Any tendency for the bonded or locked fibres to rise with the foam may be prevented by mechanically retaining the position of the fibrous structure in the mould. This may be effected for example (a) by entirely filling the mould with the fibrous mass, (b) by passing wires across the mould, (e) by providing spikes, needles or the like projecting from the mould wall as shown in Fig. 2, (d) by providing blocks 14 in the mould as shown in Fig. 5, which form cavities in the finished structure, or (e) if the fibrous material is in sheet form it may be bent into sinuous form the loops of which may be filled with the fibrous material. Specifications 341,936 and 484,798 also are referred to. According to the Specification as open to inspection under Sect. 91 preformed froth may be merely poured on to the bonded or locked fibres. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 468,861.

IPC: A61K8/22
Filed: 1933-12-01
Abstract: Mouth-wash powders comprise a stabilized oxygen-yielding compound admixed with a silver-containing compound, and preferably also with an acid substance.  The powders are mixed with water for use and yield free oxygen and free silver in the mouth.  The oxygen-yielding compound, such as urea-hydrogen peroxide, alkali peroxide-pyrophosphate, alkali perborate or alkali percarbonate is preferably free from water of crystallization and is stabilized in known manner, for example with magnesium silicate.  The silver compound may be an inorganic salt such as the nitrate or sulphate or the silver chloride-ammonia compound, or an organic salt such as the acetate, benzoate, salicylate, or p-hydroxybenzoate. Acids such as citric, tartaric, boric or phosphoric or acid compounds such as acid phosphates are employed preferably in such proportion as to neutralize only 40 to 60 per cent of the alkalinity of the oxygen-yielding compound.  Flavourings or perfumes may also be added. According to an example, 30 gms. of dehydrated sodium perborate are mixed with 1,6 grms. of the silver salt of p-hydroxybenzoic acid and 11,25 gms. of tartaric acid.

IPC: H04B17/40
Filed: 1960-10-04
Abstract: 992,690. Unattended repeaters. GENERAL ELECTRIC CO. Ltd. Sept. 28, 1961 [Oct. 4, 1960], No. 33992/60. Heading H4R. A repeater which is supplied with operating current over the transmission path, has associated therewith a first path which by-passes the repeater and a second path which is connected across the power supply conductors, the arrangement being that both paths offer a high resistance to supply current during normal operation but offer a lower resistance under " fault conditions." The latter are defined as an open-circuit repeater or a change in a parameter of the current supplied to the repeater, e.g. reverse battery. In Fig. 1, a number of repeaters 1, 2 are shown connected in a two-wire line 7, 8 carrying multi-channel carrier signals between terminal stations 5, 6. During normal operation, constant current source 11 supplies power to the line, rectifiers 25 are non-conducting and Zener diodes 24 are just conducting in the reverse direction. If repeater 1, say, develops an open-circuit, its Zener diode 24 breaks down completely so that the current supply for subsequent repeaters is maintained and the fault is signalled to station 6 using the system described in Specification 853,884. If an open-circuit occurs between repeaters 1 and 2, say, the cessation of current in the system initiates alarms at station 5. The location of the fault is achieved by applying constant voltage source 31 (of opposite polarity to the current source) to the line so that rectifier 25 conducts and with a knowledge of the resistance of the line and the reading on ammeter 32 the location of the fault can be deduced. For a short circuit or an earth fault in a repeater or the line, the output voltage of source 11 will fall and so initiate an alarm, the magnitude of the potential " loss " being an indication of the position of the fault. A four-wire system in which the phantom of the GO and Return paths is used both for audio-frequency signalling and the power supply is described with reference to Fig. 2 (not shown). A system in which a relay is connected in series with each repeater amplifier and has two contacts which replace the rectifier and Zener diode respectively is described with reference to Fig. 3 (not shown).
